International
Journal of
Computing and
Information
Sciences

Computing and Information Sciences is a peer
reviewed journal that is committed to timely publication of original
research, surveying and tutorial contributions on the analysis and
development of computing and information science. The journal is
designed mainly to serve researchers and developers, dealing with
information and computing. Papers that can provide both theoretical
analysis, along with carefully designed computational experiments, are
particularly welcome. The journal is published 2-3 times per year with
distribution to librarians, universities, research centers, researchers
in computing, mathematics, and information science. The journal
maintains strict refereeing procedures through its editorial policies in
order to publish papers of only the highest quality. The refereeing is
done by anonymous Reviewers. Often, reviews take four
months to six months to obtain, occasionally longer, and it takes an
additional several months for the publication process.

Abstract::
In this research we introduce a new approach for Arabic word disambiguation by utilizing Wikipedia as the lexical
resource for disambiguation. The nearest context for an ambiguous word is selected using Vector Space Model and
cosine similarity between the word’s context and the retrieved senses from Wikipedia. Three experiments have been
conducted to evaluate the proposed approach, two experiments use the first retrieved sentence for each sense from
Wikipedia but they use different Vector Space Model while the third experiment use the first paragraph for the
retrieved sense from Wikipedia. The experiments show that using the first retrieved paragraph is better than the
first retrieved sentence and the use of Tf-Idf VSM is better than using raw frequency VSM.
